IndexError: index -2147483648 is out of bounds for axis 0 with size 64

Hi, thanks for your excellent works! But when I try to train by run "./train.py -d /path/to/dataset -ac /config/arch/squeezesegV2.yaml -l /path/to/log", an IndexError was caught, see:
I have check the variable "proj_y", it does have a large number. I want to know what's the problem? Thanks a lots!
sorry for the late reply. it's hard to debug what it's happening there, but something in the projection does produce a strange y coordinate. I would try to check if all points are in bounds and if you need to modify the field of view (fov) of the sensor. I guess that you try to use your own dataset?
hello, I met the same problem before, -2147483648 occur may due to the NAN value in lidar points, you may try to add below code in line 116 and line 119 in common/laserscan.py
self.points = np.nan_to_num(self.points)
may it help you!
Hi, @Trexzhou , did you sovle your problem? I met the same problem like you, can you help me?
@dl19940602 ,thanks your reply, I tried your method, but it doesn't work

Did anyone solve this issue ? :)
May have found the issue.
So i used a custom dataset and within said dataset, there seems to be a point at the center of the frame with values 0 in x,y,z coordinate. The Z value being zero at this coordinate interferes with the pitch calculation ( pitch = np.arcsin(scan_z , depth) resulting 0/0 ) in laserscan.py.
Also make sure your dataset is in the right fixed frame when inferring.
You can correct me if i am wrong.
Best regards,
Rohith.
